摘要
日照市某公共建筑由于建筑功能改变,需要在15 m高度处现浇1.8 m跨后锚固悬挑梁,且新增荷载引起其他水平构件承载力不足,且需要加固处理。介绍其设计方法和施工要点,重点强调粘钢与植筋技术共同应用的双保险设计模式。工程竣工验收表明,该双保险模式在后锚固大跨度悬挑梁的设计与施工中具有较好的应用前景。
Because of the change in building functions of a public building of Rizao City, a large span cantilever beam（ l. 8 m） of post-installed fastenings needs to be casted, and other horizontal components＇ bearing capacity is insufficient due to loads increasing by the new beam. The method of the design and the main points of construction are introdueted. The paper emphasizes the application of the double insurance in the design. The project completion and acceptance shows that, the two-insurance design and construction model in the large-span cantilevered beam has a good application prospect.
